В феврале 1934 г. приказом А. Гитлера введено ношение серебряного почетного шеврона старого бойца (Ehrenwinkel für alte Kömpfer) на правом плече мундира, шинели и плаща. Его имели право носить те члены СС, которые вступили в НСДАП или СС до прихода А. Гитлера к власти — 30 января 1933 г.. Почетный шеврон для бывших военных и полицейских служащих (Ehrenwinkel für ehemalige Wehrmachts- und Polizeiangehörige) был точно таким же, но имел между лучами восьмилучевую звездочку.

Hauptsturmführer; Allgemeine SS 

It seems that this 8-year veteran should have advanced higher than captain by now.  

The possible explanation is twofold:  

First his 8-year N.S.D.A.P service ribbon applies to membership in the party, not in the SS (he has 4 years of service in the SS). And second, the chevrons on his right arm identify him as a former police officer, not a soldier.   

He is also wearing two memorial party Gau badges, including the 1925 badge (when Hitler reformed the NSDAP and took control of it) and the East Prussia Gau badge.

He also has, but does not wear, the 1925/35 Commemorative Gau badge. Gau badges were civilian in nature but the SS were allowed to wear a mixture of civilian and military badges. He also wears his gold NAZI party membership pin, and of course the distinctive black-bordered SS party member armband.
